Work
Plumb's first solo exhibition was at Gallery One, London, in 1957. He later showed with the Marlborough and Axiom galleries, but did not remain long with any dealer, a pattern his obituarists linked to his frequent changes of direction.
Plumb was among the English painters who responded directly to American abstract painting as it reached Europe in the late 1950s. His sympathies lay with large-scale, hard-edge colour-field abstraction; Plumb's Obituarist William Packer argued that the English response to the New York school was independent rather than imitative, and that Plumb's work developed the American precedent on personal terms:"American criticism has never acknowledged the intelligence and independence that characterised the English response to the New York school. Plumb's own immediate sympathy was with its large-scale, hard-edge colour-field abstraction, a commitment that was to sustain much of his own career. Here was no mere secondary imitation, rather an eager acceptance of new possibilities - of scale, simplicity and directness - to be explored and developed on purely personal terms, in the light of an English background and experience."In September 1960 Plumb was one of twenty painters in Situation: An Exhibition of British Abstract Painting at the RBA Galleries, London, an artist-organised show. The other exhibitors included Gillian Ayres, Bernard Cohen, Harold Cohen, Robyn Denny, Gordon House, John Hoyland, Gwyther Irwin, Bob Law, Henry Mundy, Richard Smith, Peter Stroud, William Turnbull and Marc Vaux. He took part in the follow-up exhibition of 1961. Situation has been characterised as a break from the landscape-rooted abstraction of the St Ives School in favour of large-scale painting responding to recent American work; the participants became known informally as the Situation Group.
In the early 1960s Plumb built his compositions from coloured adhesive tapes manufactured for the electrical industry, which were obtained for him by the collector E. J. Power. Because the tapes could be lifted and repositioned, the apparent rigour of the finished paintings was arrived at by trial and error. Edgehill (1962, Tate), shown in Situation, is built from stripes of industrial PVC tape; Tate records its medium as acrylic paint, PVC, vinyl and tape on canvas. It was given to the Tate by E. J. Power through the Friends of the Tate Gallery in 1962.
In the late 1960s and early 1970s Plumb worked with systems and chance procedures, laying linear grids and ladder-like structures across the canvas at varying angles, selecting colours at random and employing assistants to apply the acrylic. Packer described him masking or taping grids across one another and applying whatever paint came to hand, pot by pot. Plumb became dissatisfied with the impersonality of this method and in 1977 abandoned abstraction for figuration, and for landscape in particular. He later wrote that abstraction 'would not contain all that was exciting me in the outside world', and described working from drawings, pastels and watercolours made outdoors and distilled into oil paintings in the studio.
Plumb later returned to abstraction in his work. From the mid-1990s Plumb's sight was affected by macular degeneration, and in 1997 he gave up painting; he resumed about two years later, having developed ways of working around the condition. Among these were small, heavily impastoed pictures whose qualities were as much tactile as visual.
The Tate caption for Plumb's later-period work Hydrastructure - What it is which is held in their collection describes him as "one of Britain's most inventive abstract painters" explaining how this work was created: "[it] consists of broad bands of colour dragged across a canvas. Plumb applies the paint with knives and spatulas to allow for chance developments that he then reacts to. These unintended occurrences become a method for developing the character of the work."
Plumb died at Yarnscombe on 6 April 2008, aged 81.
